INSTALLATION STEP 7
Install the Light and Lens
INSTALL THE LIGHT
Install an A19 standard neck, 75 watt maximum light
bulb in the socket. The light will turn ON and remain
lit for approximately 4-1/2 minutes when power is
connected. Then the light will turn OFF.
Use standard neck Garage Door Opener bulbs for
replacement
NOTE: Use only standard light bulbs. The use of short
neck or specialty light bulbs may overheat the endpanel or
light socket.
INSTALL THE LENS
Locate and loosen (approximately 1/8" (3 mm) the two
screws near top of opener front panel.
Position lens against panel with slotted tabs directly
below screws. Slide lens up to seat tabs behind
screws.
Snap bottom tabs of lens into panel slots.
Retighten top panel screws to secure lens.
INSTALLATION STEP 8
Attach the Emergency Release Rope and
Handle
Thread one end of the rope through the hole in the top
of the red handle so “NOTICE” reads right side up as
shown. Secure with an overhand knot at least 1"
(2.5 cm) from the end of the rope to prevent slipping.
Thread the other end of the rope through the hole in
the release arm of the outer trolley.
Adjust rope length so the handle is 6 feet (1.83 m)
above the fl oor. Ensure that the rope and handle clear
the tops of all vehicles to avoid entanglement. Secure
with an overhand knot.
NOTE: If it is necessary to cut the rope, heat seal the cut
end with a match or lighter to prevent unraveling.
To prevent possible SERIOUS INJURY or DEATH from
a falling garage door:
If possible, use emergency release handle to
disengage trolley ONLY when garage door is
CLOSED. Weak or broken springs or unbalanced
door could result in an open door falling rapidly
and/or unexpectedly.
NEVER use emergency release handle unless
garage doorway is clear of persons and
obstructions.
NEVER use handle to pull door open or closed. If
rope knot becomes untied, you could fall.
To prevent possible OVERHEATING of the endpanel or
light socket:
DO NOT use short neck or specialty light bulbs.
DO NOT use halogen bulbs. Use ONLY
incandescent.
To prevent damage to the opener:
DO NOT use bulbs larger than 75W.
ONLY use A19 size bulbs.
